Composition

Expanded PTFE yarns filled with graphite powder and lubricated with silicone (egPTFE).

Characteristics

The compression packing for pumps style GB70 has a very low coefficient of friction and it is recommended for dynamic sealing. The style GB70 is able to minimize the wear of the shaft and the bushings guaranteeing a wide range of chemical compatibility. Recommended for general use services.
